The present study was intended to characterize the secondary metabolites of the endophyte isolated from the plant Schott. And to investigate the cytotoxic and other pharmacological properties of the isolated compounds as part of the drug discovery and development process. Different chromatographic techniques were adopted to isolate the bioactive compounds that were identified by spectroscopic techniques. The cytotoxic properties of the compounds were assessed in the Vero cell line via the trypan blue method. Moreover, physicochemical, pharmacokinetic, bioactivity and toxicity profiles of the compounds were also investigated through in silico approaches. After careful spectral analysis, the isolated compounds were identified as 3,5-dihydroxy-ergosta-7,22-dien-6-one (), 3,5,9-trihydroxy-ergosta-7,22-dien-6-one (), -hydroxybenzaldehyde (), 3-()-7-butyl-6,8-dihydroxy-3-pent-11-enylisochroman-1-one () and beauvericin (). An in vitro study in the Vero cell line revealed that the presence of the compounds reduced the number of cells, as well as the percentage of viable cells, in most cases. An in silico cytotoxic analysis revealed that compounds , and might be explored as cytotoxic agents. Moreover, compounds and were found to be highly mutagenic. The present study suggested that further thorough investigations are necessary to use these molecules as leads for the cytotoxic drug development process.
本研究旨在对从植物 Schott 中分离出来的内生菌的次生代谢产物进行表征,并研究分离得到的化合物的细胞毒性和其他药理学特性,作为药物发现和开发过程的一部分。采用不同的色谱技术来分离具有生物活性的化合物,这些化合物通过光谱技术进行鉴定。通过台盼蓝法评估了化合物在 Vero 细胞系中的细胞毒性。此外,还通过计算机模拟方法研究了化合物的物理化学、药代动力学、生物活性和毒性特征。经过仔细的光谱分析,分离得到的化合物被鉴定为 3,5-二羟基麦角甾-7,22-二烯-6-酮()、3,5,9-三羟基麦角甾-7,22-二烯-6-酮()、-羟基苯甲醛()、3-()-7-丁基-6,8-二羟基-3-戊-11-烯基异黄烷-1-酮()和 beauvericin()。在 Vero 细胞系中的体外研究表明,大多数情况下,这些化合物的存在减少了细胞数量和活细胞的百分比。计算机模拟细胞毒性分析表明,化合物 、 和 可能被探索作为细胞毒性剂。此外,还发现化合物 和 具有高度致突变性。本研究表明,需要进一步进行深入研究,以将这些分子用作细胞毒性药物开发过程的先导化合物。
